DR at the receiver radiography kV and mA seconds on the overall value slightly lower than CR, but the difference was not statistically significant (t=0.6784, t=0.7541;P>0.05). Conclusion: CR and DR mutual advantages and disadvantages, CR flexible, and lower cost, but the DR over CR has ...
Blurred lines: PLCs and PACs converge Much has been written about PLCs versus PACs, but is there really a difference between these terms, and does it matter? Maybe not, as PLCs continue to evol... J Payne - 《Control Engineering》 被引量: 0发表: 2015年 Blurred Lines - Where Copyright...
The qualified and high-quality piece rate of images of DR were higher than those of CR ;the film rejection rate was lower than that of CR and the difference between them was statistically significant(P<0.05).Conclusion :In the process of clinical application,the DR has a distinct advantage ...
While both CR and DR imaging techniques use digital technology for X-ray imaging and pose significant advantages over the traditional screen-film radiography, what is the difference between DR and CR X-rays? And which would be a better choice for your practice? Before making a decision, let ...
There is a fundamental difference in the purpose and manner of gain and offset correction in DR and the non-uniformity correction in CR (Figure 2). In CR, differences in stimulation and light collection efficiency are generally corrected in 1 dimension. In DR,...
In contrast, WT females were more resistant to DIO with only a small difference (B3.5 g) between chow and HFD-fed groups at the end of the dietary intervention (Fig. 1a; female HFD versus chow, P ¼ 0.09 by two-way analysis of variance (ANOVA) with post hoc Bonferroni testing). ...
The accuracy of digital storage plate mammography (CR) and full-field digital mammography (DR) was 73% and 76% for all findings ( n=100), 74%, 78% for microcalcifications ( n=50) and 72%, 74% for focal lesions ( n=50). The overall results showed no difference. Our findings ...
